IMPROVEMENT IN CAR-AXLE-BOX BRASSES.

Specification forming part of Letters Patent No. 198,115, dated December 11, 1877; application filed v September 27, 1877.

To all whom it may concern:

Be it known that I, WILTON F. J ENKINS, J r., of Richmond, in the county of Henrico, and in the State of Virginia, have invented certainnew and useful Improvements 'in Oar-Axle Boxes; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification.

My invention relates to car-axle journalboxes; and it consists in the construction of that part thereof which is commonly known as the brass in-two parts, one sliding in the other, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawing, in which- Figure 1 is a bottom. view and a plan view of my invention. Fig. 2 is a cross-section of the same.

What is commonlyknown as the brass in a car-axle journal-box is the half box or bearing on top of the journal, and this has hitherto ordinarily been made of one solid piece of metal, though sometimes it has been lined on its-under or concave side with Babbitt or other soft metal; but such lining has invariably been rigidly fastened to the main part. I construct'this brass of two parts, A and B. The part A is of the usual form, to bear against the top of the journal-box, and its lower side concave. Along each side of this part A, at the lower edge, is an inwardly-pro jectingflange or rib, a, to hold or retain the part B in place. This part B is made convex on its upper side, to fit the concavity of the flanges a a. When the parts are in' position in the journal-box, it will readily be seen that the partB can move endwise in the part.

A, which is of great advantage when the cars go around curves, as thereby the binding and strain of the journal on the brass are entirely avoided. In the flanges a are made oilpassages w 00, so that oil can easily pass in between the parts and prevent heating.

Having thus fully described my invention,

'what I claim as new, and desire to secure by Letters Patent, is

1. The journal-box brass provided with a supplemental lining, having a longitudinal movement within the same, in connection with the axle, substantially as herein set forth.

2. The combination of the part A, provided with the projecting ribs or flanges a at, having oil-passages a; w, and the sliding part B, in connection with a caraxle, for the purposes herein set forth. V

In testimony that I claim the foregoing I have hereunto set my hand this 5th day of September, 1877.

WILTON F. JENKINS, JR.
